Ah, I see what you mean. I've always tolerated alcohol well in the past though. That is the one and only time I experienced symptoms like that. When other people were throwing up or passing out I was always the one sorting the taxi. If I had a genetic predisposition towards alcohol intolerance would it not have shown up many years ago?

Thanks for your responses. I do appreciate you taking the time to help me out. It seems you are pretty indispensable around here

The burning/tingling in my left foot was worse today. It was going on all afternoon. I've booked an appointment with the doctor for 2 weeks' time. In the interim I will change the supplements and just hope it improves. If it continues to get worse...then I guess I'm screwed! Should I ask about a biopsy? It seems that is the most categorical way to determine the cause?

Feeling quite disheartened about my prospects right now...
